Non-invasive characterisation of a laser-driven positron beam
Aaron Alejo, Guillermo Marrero Samarin, Richard Warwick +6
We report on an indirect and non-invasive method to simultaneously characterise the energy-dependent emittance and source size of ultra-relativistic positron beams generated during…

General features of experiments on the dynamics of laser-driven electron-positron beams
J. R. Warwick, A. Alejo, T. Dzelzainis +14
The experimental study of the dynamics of neutral electron-positron beams is an emerging area of research, enabled by the recent results on the generation of this exotic state of m…

Experimental observation of a current-driven instability in a neutral electron-positron beam
J. Warwick, T. Dzelzainis, M. E. Dieckmann +16
We report on the first experimental observation of a current-driven instability developing in a quasi-neutral matter-antimatter beam. Strong magnetic fields ( 1 T) are measur…
